From e1ed4f2532b4e9bafb5663cccbe28033c49b2e77 Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Tue, 2 Dec 2014 12:10:14 +0100 Subject: mesa: Recompute LegalTypesMask if the GL API has changed The current code computes ctx->Array.LegalTypesMask just once, however, computing this needs to consider ctx->API so we need to make sure that the API for that context has not changed if we intend to reuse the result. The context API can change, at least, if we go through _mesa_meta_begin, since that will always force API_OPENGL_COMPAT until we call _mesa_meta_end. If any operation in between these two calls triggers a call to update_array_format, then we might be caching a value for LegalTypesMask that will not be right once we have called _mesa_meta_end and restored the context API.
